Arranging- and feeding screw-blanks



UN STATES PATENT OFFICE ELLIOT SAVAGE, 0F EAST BERLIN, CONNECTICUT.

ARRANG-ING- AN'D FEEDING SCREW-BLANKS.

Specification of Letters Patent No. 13,767, dated November 6, 1855.

To all whom 'Lt may concern:

Be it known that I, ELLIOT SAVAGE, of East Berlin, in the county ofHartford and State of Connecticut, have invented a new and usefulMachine or Apparatus for Arranging and Feeding Screw-Blanks; and I dohereby declare that the same is fully described 'and represented in thefollowing specification and the accompanying drawings, letters, figures,and references thereof.

Of such drawings Figure 1, denotes a top view of my invention; Fig. 2,an underside view of it; Fig. 3, a front end view of it;

Fig. el, a transverse section of it; Figs. 5

and 6 are side views of it.

In carrying out my invention I make use of a hopper or receiver A havingone or more of its inner sides arranged at an angle with respect to theinner surface of a reciprocating slider B as seen in the drawings, suchslider serving to constitute one side of the hopper or receiver, A, andalso one side of the long opening' or space D, extending out of thebottom of the hopper and into a passage or channel E, formed between theparallel plates o, (Z, projecting down respectively from the receiver orhopper and the slider as seen in the drawings and leading into aninclined conductor or spout, F disposed as seen in the figures. The saidinclined conductor is provided with a long slot or passage, f whichcommunicates at its upper end with the channel E in such manner that thescrew blanks may be made to pass out of the said passage and into theinclined conducto-r and take positions as represented at g, g in Figs.3, 4 and 5.

The slider B, when the machine is in use, is to have a reciprocatingrectilinear movement imparted to it, it being adapted to the hopper insuch manner as to admit of such a movement. There is affixed to thehopper a spring or presser I-I, which is arranged and made to pressagainst the outer surface of the slider as seen in the drawings, itsarrangement being such as will allow and cause the slider to be pressedup against the screw blanks when it is moved forward and to give or moveaway a little therefrom during its backward movement, the same being tofacilitate the forward movement of the screw blanks through the passageE, and into the conductor.

In operating with my machine a quantity of screw blanks is thrownpromiscuously into the hopper. This done, the slider is to be put inmotion forward and backward. By its friction against the mass of blanks,it will cause some of them to fall downward and extend through theopenings in the hopper and to stand in vertical directions and besupported by their heads resting against the two opposite inclined sidesof the hopper.

In Fig. 7, is represented a longitudinal sect-ion of the hopper, and itwill be observed by said figure, that the front end, z', of the hopper,terminates at its lower edge somewhat above its passage E, and so as topermit the blanks when in said passage to be moved out of the hopper andunderneath the said end.

By the continued movement of the slider the blanks will not only becaused to fall downward and be arranged in vertical directions, but willbe moved through the passage and successively caused to enter theinclined spout or conductor, F, and through which they will be made totravel by their gravitating power, each maintaining its verticalposition while passing longitudinally throughout said conductor. Theapparatus so made is intended to be applied to a screw threading machinein such manner as to cause the screw blanks to be delivered or fedsuccessively into the same as circumstances may require.

That I claim as my invention, is

1. The combination of the reciprocating slider, the receiver, or hopperand the inclined conductor,- the same being arranged and made to'operate together substantially as herebefore specified.

2. I also claim combining the spring proper with the slider and hopperand so as to cause the slider to operate laterally, with respect to thescrew blank as explained.

In testimony whereof I have hereunto set my signature this twenty-secondday of September A. D. 1855.

ELLIOT SAVAGE.
